An aperture ratio of the main pixel area is different from an aperture ratio of the sub-pixel area. Therefore, when an image is displayed, if positions of the main pixel area and the sub-pixel area are always arranged in a fixed manner, that is, positions of the main pixel area and the sub-pixel area in all columns are arranged in the same manner. In a horizontal direction, at a boundary between the main pixel area and the sub-pixel area, display brightness of the display panel will change, which will affect uniformity of display brightness of the display panel.
Therefore, in a current display panel technology, there is also an issue that the pixel arrangement structure in the display panel has different ways, which affects uniformity of the display brightness of the display panel, and it is urgently needed to improve.

Each column of sub-pixels includes multiple sub-pixels having different colors. Each of the sub-pixels is divided into a main pixel area 111 and a sub-pixel area 112. An area of the main pixel area 111 is not equal to an area of the sub-pixel area 112. At most four columns, a position of the main pixel area 111 and a position of the sub-pixel area 112 are alternately changed to improve uniformity of display brightness of the display panel. That is, the position of the main pixel area 111 and the position of the sub-pixel area 112 may be exchanged after one interval, two intervals, three intervals, or four intervals. The position of the main pixel area 111 and the position of the sub-pixel area 112 are alternately set in a small range to improve whether the main pixel area 111 or the sub-pixel area 112 is on the same horizontal line, which makes non-uniform display brightness on the display panel.
In an embodiment of the present application, the plurality of sub-pixels having different colors are: a red sub-pixel, a green sub-pixel, and a blue sub-pixel. In another embodiment of the present application, the plurality of the sub-pixels having different colors are: a red sub-pixel, a green sub-pixel, a blue sub-pixel, and a white sub-pixel.

In the sub-pixel arrangement structure of the third column and the sub-pixel arrangement structure of the fourth column, the sub-pixel area 112 is located above the main pixel area 111. From top to bottom, all the sub-pixel units are sequentially cycled. The fifth and sixth columns of sub-pixel arrangement structures are the same as the first and second columns of sub-pixel arrangement structures, and the third and four columns of the sub-pixel arrangement structures are the same as the seventh and eight columns of the sub-pixel arrangement structures, and are sequentially cycled. In another embodiment, referring to FIG. 3, the area of the main pixel area 111 is larger than the area of the sub-pixel area 112. If in the sub-pixel arrangement structure of the first column, the sub-pixel arrangement structure of the second column, and the sub-pixel arrangement structure of the third column, the main pixel area 111 is located above the sub-pixel area 112. From top to bottom, all sub-pixel units are sequentially cycled. In the fourth column of the sub-pixel arrangement, the fifth column of the sub-pixel arrangement, and the sixth column of the sub-pixel arrangement, the sub-pixel area 112 is located above the main pixel area 111. From top to bottom, all sub-pixel units are sequentially cycled. The seventh, eighth, and ninth columns of the sub-pixel arrangement structures are the same as the first, second, and third columns of the sub-pixel arrangement structures, and the tenth, eleventh, and twelfth columns of the sub-pixel arrangement structures are the same as the fourth, fifth, sixth columns of the sub-pixel arrangement structure, and are sequentially cycled. In another embodiment, referring to FIG. 4, the area of the main pixel area 111 is larger than the area of the sub-pixel area 112. If in the sub-pixel arrangement structure of the first column, the sub-pixel arrangement structure of the second column, the sub-pixel arrangement structure of the third column, and the sub-pixel arrangement structure of the fourth column, the main pixel area 111 is located above the sub-pixel area 112. From top to bottom, all sub-pixel units are sequentially cycled. In the fifth column of the sub-pixel arrangement, the sixth column of the sub-pixel arrangement, the seventh column of the sub-pixel arrangement, and the eighth column of the sub-pixel arrangement, the sub-pixel area 112 is located above the main pixel area 111. From top to bottom, all sub-pixel units are cycled in turn; the ninth, tenth, eleventh, and twelve-column sub-pixel arrangement structures are the same as the first, second, third, and fourth-column sub-pixel arrangement structures. The thirteenth, fourteenth, fifteenth, and sixteenth-column sub-pixel arrangement structures are the same as the fifth, sixth, seventh, and eighth-column of the sub-pixel arrangement structures.
Further, in another embodiment, referring to FIG. 5, an area of the main pixel area111 is smaller than an area of the sub-pixel area 112. That is, the aperture ratio of the main pixel area 111 is smaller than the aperture ratio of the sub-pixel area 112. The brightness of the main pixel area 111 is smaller than the brightness of the sub-pixel area 112. Similarly, the sub-pixel arrangement structure is spaced at most four columns, and the position of the main pixel area 111 and the position of the sub-pixel area 112 are alternately changed to form four different pixel arrangement structures.
Specifically, each of the main pixel areas 111 and each of the sub-pixel areas 112 further include four pixel domains, that is, a first pixel domain, a second pixel domain, a third pixel domain, and a fourth pixel domain. The areas of the main pixel domains may be equal or not completely equal. The area of each sub-pixel domain may also be equal or not completely equal. However, between the main pixel domains, at least two of the main pixel domains have the same area. Between the sub-pixel domains, at least two of the sub-pixel domains have the same area. Referring to FIG. 6 and FIG. 7, the main pixel area is divided into a first main pixel area 1111, a second main pixel area 1112, a third main pixel area 1113, and a fourth main pixel area 1114. The sub-pixel area is divided into a first sub-pixel area 1121, a second sub-pixel area 1122, a third sub-pixel area 1123, and a fourth sub-pixel area 1124. In FIG. 6, the areas of the first main pixel domain 1111, the second main pixel domain 1112, the third main pixel domain 1113, and the fourth main pixel domain 1114 are equal. The first sub-pixel domain 1121, the second sub-pixel domain 1122, the third sub-pixel domain 1123, and the fourth sub-pixel domain 1124 have the same area.
In FIG. 7, the areas of the first main pixel domain 1111 and the fourth main pixel domain 1114 are equal. Areas of the second main pixel domain 1112 and the third main pixel domain 1113 are equal. The first sub-pixel domain 1121 and the fourth sub-pixel domain 1124 have the same area. Areas of the second sub-pixel domain 1122 and the third sub-pixel domain 1123 are equal. It is preferred that the areas of the main pixel domains are the same and the areas of the sub-pixel domains are the same.
Further, the four pixel domains of each of the main pixel areas 111 and each of the sub-pixel areas 112 are electrically connected to a trunk electrode having a cross shape. The trunk electrode is a boundary dividing a pixel domain. Each of the pixel domains includes a plurality of auxiliary electrodes. The trunk electrode and the auxiliary electrodes together form a fish-bone pixel electrode.
Further, a distance between the adjacent auxiliary electrodes includes many different cases. That is, the auxiliary electrodes have a plurality of different densities. Referring to FIG. 8, a density of auxiliary electrodes in each of pixel domains is smaller than the density of the auxiliary electrodes in each of the above pixel domains. Similarly, the density of the auxiliary electrodes in each of the pixel domains may continue to increase or decrease. Further, in each of the pixel domains, the auxiliary electrodes may extend in the same direction or may extend in different directions. When the auxiliary electrodes extend in different directions, deflection directions of liquid crystal molecules in the four different pixel domains are also different due to a driving voltage, so that a liquid crystal display panel has larger viewing angles.
An embodiment of the present application further provides a display panel, including: a color filter substrate, an array substrate disposed directly opposite to the color filter substrate, and a liquid crystal layer disposed between the color filter substrate and the array substrate. The array substrate is provided with all the features of the pixel arrangement structure described above.
Therefore, the beneficial effects are as follows. First, the pixel arrangement structure provided by the embodiments of the present application includes sub-pixels having multiple colors. Each of the sub-pixels is divided into a main pixel area and a sub-pixel area. The area of the main pixel area is not equal to the area of the sub-pixel area. At most every four columns, that is, one column, two columns, three columns, or four columns, the position of the main pixel area and the position of the sub-pixel area change alternately. This can not only alleviate the low color shift design of the display panel, but also improve uniformity of display brightness of the display panel. Secondly, in the pixel arrangement structure provided in the embodiments of the present application, the area of the main pixel area is larger or smaller than the area of the sub-pixel area. Each of the main pixel areas and each of the sub-pixel areas are further divided into four pixel domains: a first pixel domain, a second pixel domain, a third pixel domain, and a fourth pixel domain. The areas of at least two pixel domains are equal, and the auxiliary electrodes include at least one density, which can further improve display brightness of the display panel.
